DINNER-PAIL.

Specification of Letters Patent.

Patented June 12, 191%.

Application filed January 31, 1917. Serial No. 145,686.

' To all whom it may concern I Be it known that I, WILLIAM H. Don"OASTER, a citizen of the United States, residing at Brownington, in thecounty of Orleans, State of Vermont, have invented a new and usefulDinner-Pail; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The present invention relates to a dinner pail, and has for its objectto provide a device of this character which embodies novel features ofconstruction whereby provision is made forcarrying some form of liquidor beverage and maintaining it in either a hot or a cold condition for aconsiderable length *of time.

Further objects of the invention are, to provide a dinner pail which iscomparatively simple and inexpensive in its construction,

which can be taken apart and thoroughly cleansed so that the liquidreceiving chamber will never become sour, which can be convenientlycarried from place to place, and which confines the liquid or beveragein such a manner that it does not occupy an ,un-

reasonable amount of space and does not interfere with the otherportions of the lunch.

With these and other objects in view, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in

which Figure 1 is a vertical sectional View through a dinner pailconstructed in accordance with the invention.

Fig. 2 is a top plan view of the same with the outer cover removed.

Fig. 3 isa detail view of one of the locking wings for theyahnularclosure of the liquid receiving chamber.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views of the drawings by the same referencecharacters.

Specifically describing the present embodi- ,ment of the invention, thereference char acter A designates an outer shell which is.

provided with a cpnventional handle 1 for convenience in carrying, andwhich is adapted to be closed at the top by aremovable flanged cover 2,This outer shell A may be of any desired shapeor configuration, althoughin the present instance it is shown as being cylindrical in form. Thesides and bottom of the shell have a triple walled formation, in-

shell A is a food compartment B-which is' correspondingly shaped, butsmaller in di ameter and shorter in length, so that a liquid receivingspace 8 is provided between the food compartment and the outer shell.The top of the food compartment B is designed to be closed by aremovable flanged cover 9, and the sides and bottom thereof have adouble walled construction, being formed with an inner wall 10 and aspaced outer wall 11 which are connected at suitable intervals by braces12, and cooperate with each other to provide a vacuum space 13. Spacingarms 14 project from the bottom and sides of the food compartment B andare designed to engage the inner walls 4c of the outer shell A to holdthe food compartment in a properly spaced relation thereto andaccurately define the liquid receiving chamber 8 which surrounds thesides and bottom of the food compartment. If desired, the bottom andouter shell A may be provided with positioning depressions 15 to receivethe extremities of the spacing arms 14 on the bottom of the foodcompartment and codperatc therewith to prevent anypossibility of thefood compartment becoming loose within the outer chamber and rattling orjarring about therein when the dinner pail is being carried. In order toinsure a seating of the arms 1d within the positioning depressions 15,the inner side walls 4: of the outer shell may have short verticalgrooves 16 pressed therefrom to receive the extremities of the sidespacing arms 14. With such a construction the food compartment must bebrought into proper position for seating the lower spacing arms 14 inthe de ressions 15 before it can be lowered the ful amount in the shell.

An upwardly facing shoulder 17 is provided at the top of the foodcompartment B, said shoulder being at substantially the same elevationas the shoulder 7 and the outer shell when the parts are assembled.

An annular closure 18 is provided for the upper end. oftheliquidreceiving chamber 8, said closure being flanged at the outerside thereof, as indicated at 18 for engagemeut with the outer shell A,while the inner edge thereof projects over the shoulder 17 of the foodcompartment B. A suitable packing ring 15) ot'cork or-r'ulibenmay be:pplied to the lower face of the closure 18 for engagement with theshoulder 17 of the food compartment '0 provide a tight joint therewithand prevent leakage of the liquid confined within the chamber 8. Handles20 are applied to the ring 18 for convenience in manipulating the same,and the said ring is provided with an air vent 21 which is normallyclosed by a plug 22. but which can be opened to permit the ingress ofair when it is desired to withdraw the liquid within the chamber 8through the discharge 'l'aucet i For the purpose ol locking,the annularclosure .18 firmly in position. a series of gwings 2t are hinged at 25to the side walls of the outer shell A at a point above the shoulder '7,said wings being adapted either to be swung away from the closure 18, orswung outwardly" into engagement with the top thereof to hold theclosure lirmly seated .in position. ill desired, the lower edges ol thelock-mgavmgs ll. may. be. provided with resilient arms El" arranged to'lricta'inally engage the closuredS to hold the parts in operativeposition even though the pail may be subjected to constant.jarring andvibra tion such as, would otherwise tend to cause the parts-lov workloose. The discharge lancet 23% is arranged al the hollomol the outershell and extends through the vacuui chamber 5, the valve ol' the faucetbeing controlled l v a stem it; which extends upwardly through thevacuum chamber and projects above the shoulder 7, being provided at itsextremity with a handle 27. The l'aucet is thus controlled from the topof (he pail and the arrangement is such that ii is not neeessauv to tilto tip the pail except lo a very slight extent in order to com plclclydrain the liquid contents From the chamber 8. tubular casing 38prel'erably surrou uls lhe valve stem 26 and eXtendsbctween the l'auceti3 and the top of the vacuum chambers, [hereby preventing thearrangement from inlerl'erin; with the maiu lenance ol a vacuum withinthe space be,- tween the double. walls ol the shell. H desired. a'drinking cup 29 may he carried in the space between the cover 9 of thefood compartment B and the cover 2 of the outer shell A.

lers Patent, is t The solid parts of the lunch aredesigned to be packedwithin the interior or the t'ood compartment B, and a removable tray 30is shown as supported therein upon suitable shoulders 31. lVhen theparts areasserhbled, the food compartment 13 is held securely inposition by the annular closure 18 of the liquid receiving chamber 8.said annular elosure being in turn locked in position by the swingingwine's 2t. All looseness isthus taken up so that the pail can be carriedwithout rattling otthe parts, and the liquid is tightly conhned withinthe chamber 8 so that it can not leak into any other parts of the pail,and does not interfere with the roper packing of the solid portions ofthe lunch. It will also be noted that the liquid 'is conlined betweentwo vacuum chambers,

proper access can not be had to the interior r of the'chamber for thepurpose of cleansing *he same. I

Having thus described theinventiomwhat I claim as new-and desire tosecure by Letl. A dinner pail including an outer shell open at the topthereof. an inner food compartment fitted removably within the outershell and spaced therefrom to provide a liquid receiving chamber betweenthe two members, an annular closure for the liquid receiving chamber.said annularclos'ure engaging the outer shell and overlapping the foodcompartment to retain the latter in position, and locking means'upon theouter shell for engaging the annular cove" to retain the latter inposition.
